Mr. Wong wants to purchase 12 new smoke detectors for his house. Store A sells each smoke detector for $17 and Store B sells each smoke detector for $24. If Mr. Wong purchases all his smoke detectors at Store A, how much less will he spend than if he purchased all the smoke detectors at Store B?

Answers

Answer 1

Answer:

$84

Step-by-step explanation:

so for store A, you would do $17*12 smoke detectors,  Which would give you $204. For store B you would do $24*12 smoke detectors. That is $288. Now all you do is 288-204=84. You would save $84 dollars going to store A

Answer 2

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The amount less spend by buying in store A than in store B is $84

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The number of smoke detectors to be purchased.

= 12

Store A:
Cost of one smoke detector = $17

Cost of 12 smoke detectors.

= 12 x 17

= $204

Store B:

Cost of one smoke detector = $24

Cost of 12 smoke detectors.

= 12 x 24

= $288

Now,

The difference between the cost of 12 smoke detectors from store A to store B.

= $288 - $204

= $84

Thus,

The amount less spend by buying in store A than in store B is $84

The number is .

To find:

The correct values for each blank.

Solution:

The given number is .

We know that, 10 lies between two consecutive perfect squares 9 and 16, . repeating is located between the square roots of these two numbers.

This means  repeating is located between 3 and 4.

So,  repeating is less than 5.

Therefore, Blank-1=9, Blank-2=16, Blank-3=3 and Blank-4=4.

The number √10 is less than 5.

Because 10 lies between two consecutive perfect squares 3 and 4.

What is square root of a number?

A square root of a number is a value that multiplied by itself gives the same number.

Given that;

The number is √10.

Now,

The value of √10 = 3.16

Which is less than 5.

Hence, 3.16 < 5

Since, The value of 3² = 9

And, The value of 4² = 16

Thus,

3² < 10 < 4²

So, The number √10 is less than 5.

Because 10 lies between two consecutive perfect squares 3 and 4.

Hence,

d-6+10=2/3(d+10)

d+4=2/3(d+10)

3/2(d)+4=d+10

3/2(d)-d=10-4
